Ultrasonic Testing
Clearly, ultrasonic testing of pristine billets of steel not being terribly useful, this is a training exercise rather than an actual use of non-destructive testing as such. Still, rather interesting.
This is a testing method called ultrasonic inspection whereby the probe (held in hand) is moved along a smooth surface of a metal object. It uses sound waves and their reflections to find hidden cracks. Ultrasonic testing is very useful for finding sub-surface defects in steel, aluminium, and other metals. We use it in the underground for train axles (on wheelsets) and the like.
